This is a system of equations. The best way to solve it is by realizing that you have two equations equal to y. Since y = y, it follows that

. Solving for x, you get 4.

Then, substitute 4 into one of the original equations to find y.

.
The solution is

. I have attached a graphical representation of the solution as well.

Answer:
A.) 2x - 9x - 30 = -6
Step-by-step explanation:
hello !
to solve this system of equations, first, we substitute the equation
to the <em>y </em>variable in the equation
. Therefore, we get:

now, we simplify by multiplying -3 to the variables inside the parenthesis, which, in short, is also called the distributive property. thus, we get:

An equivalent ratio of 64:60 is 16:15.
